Abstract

Amortisseur hydraulique comportant un corps cylindrique (2) disposé suivant un axe principal, un piston fixée (4) fixé à l'extrémité d'une tige axiale (6), coulissant dans le corps (2) en séparant une chambre de détente (10) du côté de la tige (6) d'une chambre de compression (8) du côté opposé à cette tige (6), ce piston (4) comprenant un passage principal avec restriction (12) d'une chambre à l'autre, un passage secondaire d'une chambre à l'autre (8, 10), comprenant un orifice réglable (16), et un système de masselottes pressé par des ressorts, qui se déplace par inertie dans une direction radiale sous l'effet d'accélérations radiales de l'amortisseur, en modifiant la section de l'orifice réglable (16).Hydraulic shock absorber comprising a cylindrical body (2) arranged along a main axis, a fixed piston (4) fixed to the end of an axial rod (6), sliding in the body (2) by separating an expansion chamber (10 ) on the side of the rod (6) of a compression chamber (8) on the side opposite this rod (6), this piston (4) comprising a main passage with restriction (12) from one chamber to the other , a secondary passage from one chamber to another (8, 10), comprising an adjustable orifice (16), and a system of weights pressed by springs, which moves by inertia in a radial direction under the effect of '' radial accelerations of the shock absorber, by modifying the section of the adjustable orifice (16).
